java + jfreechart + itextpdf创建折线图饼图并导出为pdf
2024-05-13 16:17:08
一、添加需要的maven依赖
<!--用于生成pdf--> <dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.9</version> </dependency> <dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.2.0</version> </dependency> <!--用于jfreechart生成图片 --> <dependency><groupId>org.jfree</groupId><artifactId>jfreechart</artifactId><version>1.5.0</version> </dependency>

五、使用到的dto
public class VehicleIndex {}
@Data
public class VehicleIndex1 extends VehicleIndex{private String indexValue;private String chainValue;
}
@Data
public class VehicleIndex2 extends VehicleIndex1{private String indexName;}
@Data
public class VehicleIndex3 extends VehicleIndex{private String indexName;private String indexValue;
}
